Forget 3hrs free. We lived in the tropics in Australia with a ~6kW system and often had negative quarterly invoices (i.e. got paid by our retailer) ... esp. in winter months. Aircon, pool, appliances all electric. At the very least the pool pump ran free all year round.
Edit: should add, that's straight solar no battery
What are some direct solar appliances or equipment you've found that you like?
We live in a deep valley where it snows a ton in Canada, and with 7.2kw of panels and no battery we only get a bill in winter. For the entire year our power bill is $500, and we have heat pump heat, and disconnected the natural gas.
We just got a very high efficiency wood stove, I expect we will now have no electricity bill each year.
